Battery charger for Stop Start battery

    The URL www.ctek.com is interesting.

    It says the MXS-5 model supports stop/start (+AGM etc) but the 7.0 model doesn't really say stop/start. (But it does mention AGM, which I thought implies stop/start batteries)

    I bought the 5 model based on this thread...

      I would also be interested in understanding what the difference is since it's looks like a *less* featured charger than the MX5 etc

      Reading on the CTEK site it says it's "Optimized for AGM and EFB-batteries"

      searching EFB led me here:
      AGM & EFB Automotive Batteries Explained - Yuasa battery

      The short version is that EFB deals with lower charge better than AGM batteries (and stop start vehicles tend to work the battery much harder).

      So (and I'm totally guessing here) maybe EFB can/could be charged differently to AGM hence a new charger type with added smarts to better deal with the different (newer) battery type??

      Of course the obvious question is how much difference does it actually make?

      If it has an engine or heartbeat it's going to cost you.

        It is what is put in Bluemotion vehicles that have the stop start function. Mine is a Varta AGM Vw part no 7PO 915 105 and is what I told the Battery World guy.

          My R36 has the same Varta AGM 7P0 915 105 C battery with spec 92Ah 520A DIN 850A EN/SAE

          Been using MXS 7.0 charger with AGM mode for 2 years.

            I dont doubt you at all am merely repeating what a so called expert has told me and asked for verification from the manufacturer
            Will post the answer if and when I get it

            Mine is 68Ah 38A 680A EN/SAE

              Have a brief reply from Ctek which says " You can with good result use your MXS 7,0 to your Varta AGM battery. This will not harm the battery."

              So guess its OK and Battery World are not entirely correct.

                I agree with you. I'm using 10 years old CTek to charge the AGM battery without any issue.
                The Ctek charger cost more these days for some reason, but there are also Bosch and Projecta with their consumer orientated chargers. The Ctek is probably the best suited, if you charge the battery in the driveway, since it's environmentally sealed.

                  Repco seem to knock 50% or so off the prices with some regularity. I got one the other week to replace an Aldi charger. Which for $30 was ok as a basic item. The Ctek is another world though.

                    Bought my MXS 7.0 at Repco sale for $159. Cheaper than online at the time

                      This is sort of like saying "sure you can use your OEM wheels with your car with good results.... but we have newer ones...".

                      The MXS series specifically work with the AGM batteries, so that's no great surprise. I'd still be interested in what the EFB batteries chargers bring to the table over the AGM types and if there is any benefit in the "stop/start" charger vs the MXS when it comes to charging AGM batteries.

                      ...which of course leads to the next question...

                      Does VW use EFB? Or are they even available in Australia otherwise?

                      If it has an engine or heartbeat it's going to cost you.

                          The EFB batteries are just a bit improved version of the std lead acid flooded batteries. So, any CTek charger will charge it just fine, without any ill affect. The AGM batteries are superior to EFB batteries.

                          From the Tiguan with ss technology.
                          The charging characteristic of the alternator is not any different to ordinary flooded battery, with exemption to the higher current, to allow quick charging.
